Environmental conditions.

The device is designed to

operate at a temperature of -25÷55°C with air humidity

below 90%. Exceeding the operating limits may result in

incorrect operation or damage to the multimeter.

An opening of 92×92 mm should be made in the panel, and the

thickness of the material used to make the panel should not ex-

ceed 5 mm.
